An array having more than two dimensions is called a multidimensional array in MATLAB. Multidimensional arrays in MATLAB are an extension of the normal two-dimensional matrix. Generally to generate a multidimensional array, we first create a two-dimensional array and extend it. For example, let's create a two-dimensional array a.

The variables you created above were all scalars (only one value for each variable). MATLAB was actually built around the use of vectors and arrays, so it is very efficient at processing vectors and arrays. Vectors are lists of numbers. Create a vector called v1 with three elements (note the use of the square brackets): >> v1 = [ 4 2 9] v1 =
